About $400 for a mess like this, unless you do it yourself, but we had our own work crew (independent Contractors) and having someone to rely on to remove the junk took a lot of pressure off of us when we did encounter things like this. 

Here's where  energy modeling and rating systems like the Dept of Energy Home Score helps with marketing and can lessen sticker shock in any state: Imagine there are two homes for sale that are pretty identical in size, location, year built etc.

A decade back I encountered vastly a higher percent of renter families saving up tens of thousands of dollars and moving out of their apt within a few years into their first homes.These days I rarely ever come across a family that is even interested in saving to close on their first home.

In most houses we encounter, freeze damage in drain lines is ALMOST always confined to toilets (look for fine or major cracks in the porcelain) or traps.  

Has anyone used stickers as part of their marketing?

Here are some of the code rules I encountered: There was a common area between the two units (laundry and back door) - because of this both units had to have doors that were fire rated.

Have you ever encountered this?

@Jeff Copeland, as a Florida Realtor, if you were purchasing in another state, would you pay "Full Sticker" buyer agent commission or allow any of your close family or friends to pay "Full Sticker" buyer agent commission?

I will say this that this specific story was a good example of prudence on the part of the gun owner for his specific encounter.

One deviation for ROI that I often encounter which makes sense to me is when figuring in the proceeds from resale of the property (this is when you monetize your amortization and appreciation and can calculate the $ benefit of both as a % of your original investment).
